[client-v2] Resource release

[chernser]

Description

Recently we have found that while using queryRecords leads to error when user forget to close Records object what leads to a connection leaking. We need to review and put some guard rails even this a misuse problem.

We need to:

• Think about detecting orphan response objects somehow
• We need to put more information into ConnectionRequestTimeoutException because it indicates that pool is empty
• We need to review Insert/Command operation code to make sure resource are release as soon as they can.
